You should see what a scatter of 5 US pennies makes with a wristrocket. If only one hits you, it will leave a scar for life. I'll never forget the look on my uncles face as the first shot of the quail season went out of his 16 ga. He had forgotten the $100 dollar bill that was hidden in the barrel...as the paper fluttered to the ground, he had tears in his eyes. Picked up enough of it, took it to the bank and got a new one since he found more than 2/3 of the thing...loaded with .50cent coins! Not very realistic but definitely bad ass....
